Your blogpost might benefit from explaining further the following line: "Special relativity says that the rocket has a different coordinate frame than the space stations. In particular the x axis, which corresponds to all the points in space at the same rocket-time, is not the same as the x-axis for the space stations." I'm on the lookout for an explanation of why FTL=time-travel that I'll finally understand. However in your blogpost my limited knowledge of Special relativity fails to make sense of the whole argument.
